摘要
本文建立了波浪、水流与淤泥质底床三者相互作用的理论模型.在此基础上,用数值方法求得了波浪、水流与淤泥质海床三者相互作用系统的色散关系.研究了波流共同作用下底泥的响应特征,包括速度场、压力场、界面波高和相位差,讨论了底泥响应的“共振”现象,并对影响响应特征的因素进了全面分析.
This paper presents a theoretical model for the interactions among waves, current and bed mud. By the model, the dispersion relation for the interactive system among waves, current and bed mud is calculated. The responses of bed mud to waves and current, including velocity and pressure distribution, amplitude rate, phase lag and the system's resonance are investigated. The influence of current velocity, density and thickness of mud layer, wave period and water depth on the responses of bed mud are analysed comprehensively.
